SAR for hands, wrists, feet and ankles is averaged over any 10 grams of tissue defined as a tissue volume in the shape of a cube. Occupational/Controlled Environments: Are defined as locations where there is exposure that may be incurred by people who are aware of the potential for exposure, (i.e. as a result of employment or occupation). General Population/Uncontrolled Environments: Are defined as locations where there is the exposure of individuals who have no knowledge or control of their exposure.

Justification of the extended calibration Referring to KDB 865664 D01, if dipoles are verified in retum loss(< -20dB, within 20% of prior calibration), and inimpedance(within S ohm of prior calibration), the annual calibration is not necessary and the calibration interval canbe extended. <Head 450MHz> Return Loss (dB) Delta (%)ImpedanceDelta(ohm) Date of Measurement -25.95-45.0-Feb. 21, 2025 -26.25-1.1645.870.87Feb. 20, 2026 The return loss is <-20dB, within 20% of prior calibration; the impedance is within 5 ohm of prior calibration. Therefore the verification result should support extended calibration. ※※END OF THE REPORT※※ ※※END OF THE REPORT※※
